Parent Selection Cluster Based Algorithm for Wireless Sensor Network
In this paper, the authors propose a Parent sElection Cluster based Algorithm (PECA) for improving the sensor network lifetime. PECA achieves a good performance in terms of lifetime by balancing the energy load among all the nodes. One way to support efficient communication between sensors is to organize the network into several groups, called clusters, with each cluster electing one node as the head of cluster. In this algorithm, they cluster the network by using new factors and then construct a spanning tree for sending aggregated data to the base station which can better handle the heterogeneous energy capacities. PECA partitions the network into clusters; the cluster contains, CH, sub-CH nodes; thus extends network lifetime.
